“In science we may start with experimental results, data, observations,...” — Carl Sagan Quote

“In science we may start with experimental results, data, observations, measurements, ‘facts’. We invent, if we can, a rich array of possible explanations and systematically confront each explanation with the facts.”

“The many sorrows of our recent history suggest that we humans have a learning disability.”

“Many of the dangers we face indeed arise from science and technology—but, more fundamentally, because we have become powerful without becoming commensurately wise. The world-altering powers that technology has delivered into our hands now require a degree of consideration and foresight that has never before been asked of us.”
